PROBLEM TO BE SOLVED: To provide a method for producing ferrocoke for metallurgy, which comprises dry distillation of a molded article comprising a carbon material and iron ore, and by which the deterioration in the strength of the ferrocoke can be prevented, even when the reduction of the iron ore proceeds. SOLUTION: The method for producing ferrocoke for metallurgical by dry distillation of a molded article comprising a carbon material and iron ore includes separating the carbon material into a high inert carbon material with an inert content of≥40 mass% and a low inert carbon material with an inert content lower than that of the high inert carbon material; mixing thus separated high inert carbon material with at least a part of the iron ore to impregnate the high inert carbon material with the iron ore; then mixing the low inert carbon material with the remaining iron ore to produce a molded article. The carbon material is preferably separated into a high inert carbon material and a low inert carbon material according to particle size thereof. COPYRIGHT: (C)2010,JPO&INPIT |
